Apple is again rumored to be releasing an iPhone 5S and a larger 5-inch iPhone in 2013 in a Sina Tech report relayed by Bright Wire.

● A source told Chinese mobile phone information site Laoyaoba.com that he has seen the iPhone 5S and iPhone 6 at Apple's suppliers. Both models may be released in 2013, according to the website's microblog on Thursday evening.
● The source noted that the iPhone 5S resembles the iPhone 5, and the five-inch iPhone 6 is lighter and thinner.

A recent iLounge report said Apple is planning to release an iPhone 5S and a cheaper model for emerging markets in 2013. In addition, Apple was said to be prototyping a 4.7-inch device as a "just in case / Plan B" hedge against the increasing popularity of large screen sizes.
